The lads hide behind a bush and speak through a concealed tube to mimic the sound of a workman stuck down a man-hole.

Confused passers-by try to help the man out, including some cyclists.

Eventually, the jokers recognise someone they know.

All is then revealed as they come out from their cover.

And unlike Bart Simpson, they do not end up actually stuck down the hole in a bid to remove evidence of their prank, and willingly come clean.

Ginger Cal and Friends’ antics have proved popular since the builders started adding videos to Facebook.

Other pranks include tying money to string and dragging it round the floor of Newcastle Central Station, and one where they pretend to be a pensioner who falls over on the street - before running away from shoppers who try to help him.
